Standardization. — The standardizing of milk or cream means making it contain a definite per cent, of fat. This may be done by adding cream or rich milk to that which is low in its fat content, or MARKETING MILK 59 THE RELATIVE AMOUNT OF CREAM ON MILK STANDARDIZED TO CONTAIN DEFINITE PER CENTS. OF FAT diluting that which is high with skim milk or cream and milk having lower per cent, of fat. Michels gives the following: FORMULAS FOR STANDARDIZING MILK AND CREAM Problem i. — A producer contracts... to deliver 450 pounds of milk testing 4.0 per cent. fat. His milk as it comes from the herd tests 4.3 per cent. How many pounds skim milk must he add to this to re- duce it to 4.0 per cent.? Formula: X=(^dJLE\—A, i in which X = number pounds skim milk to be added. A = number pounds original milk. B = test of original milk. C = test desired. 6o FIRST LESSONS IN DAIRYING Substituting, we get : X = {^^^) - 450 = 33.75 pounds. Problem 2. — Suppose that the 450 pounds of milk tested 4.0 per cent, and it is desired to raise it to 4.5 per cent, by extracting skim milk; the amount of skim milk to be extracted is determined from the following formula : in which X equals number of pounds of skim milk to be extracted, and A, B, and C are the same as in the preceding formula.
